Gun Mayhem
About Gun Mayhem Unblocked
Gun Mayhem unblocked is available to play for free online. Gun Mayhem is a chaotic 2D platform shooter where the goal isn't to eliminate opponents, but to blast them off floating platforms into the abyss below. Inspired by Super Smash Bros' knockout mechanics, this explosive arena fighter combines precise platforming with intense firearms combat. The game features a comprehensive campaign mode with dozens of challenging levels against AI opponents, local multiplayer supporting up to 4 players for couch co-op mayhem, an arsenal of diverse weapons from pistols and shotguns to rocket launchers and laser guns, and unlockable characters and customization options. Each match takes place on destructible platforms suspended over deadly drops. Shoot enemies to build up their damage percentage - higher damage means they'll fly farther when hit. Collect weapon crates that drop powerful firearms and explosive gadgets. Master movement to stay on platforms while knocking opponents off edges. With its simple controls yet deep tactical gameplay, explosive power-ups, and satisfying ragdoll physics, Gun Mayhem delivers endless replayability whether playing solo campaigns or competitive local multiplayer battles.
How to Play
- Movement controls: Use arrow keys or WASD to move and jump. Player 1 uses WASD, Player 2 uses arrow keys in multiplayer. Jump repeatedly to double-jump.
- Combat mechanics: Shoot to build enemy damage percentage (shown above their head). Higher damage means farther knockback. Knock opponents off all platform edges to score.
- Weapon pickups: Colored crates drop onto platforms containing weapons. Break them to equip new guns. Each weapon has different fire rate, damage, and knockback.
- Win conditions: In Campaign, defeat waves of enemies. In Versus mode, be the last player standing or score the most knockouts. Master movement and timing to dominate the mayhem!
